Thisinvention' relates to yarn winding-machines, and more particularly to that class of:

winding machines wherein the-yarn package being formed 15 surface drlven" fr ct onally Y from a rotating driving; ro'll.

. It'is now the ordinary practice to windyarn which is to beused as thewarp threads in weaving, into packages, and support these packages 1n a creel frame flOm'WlllCh a multiplicityof threads are drawn and wound SldG by side on a warp beam. If the yarn packages contain different; amounts ofyarn it results in the frequent stoppage of the warping machine to piece up ends and consequent loss of I These parts may be of usual constructionproduction.

One of the objects of the presentinvention is to improve yarn winding machines in order that yarn packages of predetermined s1ze may be produced sothat when a multiplicity of the premature 25 comes effective to stop the winding operation I I of any one yarn package'when that yarn packsuch packages of the same yarn size are placed in the creel frame and wound upon the warp beam, fewer or substantially no stoppages of the Warping machine become necessary due to running out of some of the yam, 1

An improved feature of the presentinvention consists in automatic means which be:

age has reached a predetermined size.

The lnvention and newv combination; of

parts will best be made clear from the following description and accompanying drawings of one good formthereof.

In the drawings-fi i V r Fig. 1 'is a .perspective view with parts brokenj'away showing sufficientportions of winding machine" containing the present-in-,

the yarn winding machine containing the present invention tomake clear the construction and operation thereof; I p

The general construction of the yarn wind 'ing machine may be similar to those of similar character now well known, and as shown such machine comprises the frame '1 which may be of a size and extent to support a'plu rality. of yarn winding mechanisms, only one of which is shown in the drawings; I Mounted in a suitable'bracket 2 secured to the machine frame are the bearing arms 3 for a driving roll 4 which constitutes the driving means for the yarn package which normally rests-thereon during. the winding operation.

and the driving roll t may be driven from any EDWARD A. CUNNIFF, a qmsq'wmm connncrrrcur, ASSIGNOR T0 IBIG-ELOW- suitable source ofpower now well known, and

Extending betweensuitable uprights 10 of the machine frame is a transversely extending shaftllon whichis' loosely mounted an;

arm 12 which supports the'yarn holder." The the arms 13 having a suitable bearing for the yarn holder may be of any of the present well i known constructions and as'shown in the present instance of the invention comprises tion being such that as the yarn is wound upon i the yarn holder or core 14 by surface engage- 5 ment with the driving roll, the yarn holder will be gradually raised as the yarn package increases injsize.

i The yarn a-mayzbe supplied from any suitable source as for instance from the spools 15 ffromwhi'ch the yarn asses through and over, suitable. guides: 16,1 .18, and. then under a The parts constltutingthe yarn holder may be variously contrived;'- the essential in this respect being that the-yarn holder will. be gradually raised as the yarnpackages 'in-' guide bar 19 from which the yarn passes to the yarn guide 9, and suitable traversing mechanism may be employed as usual in this class of machine and now well known, for traversing the yarn longitudinally of the yarn holder or core ll. The parts so far described may be of usual construction and the details thereof form no essential part ofthe present invention.

The lifter frame 6 has mounted more clearly shown by Fig at, the dog 20 which may be supported for rocking movement upon a shaft 21 carried'by the lifter frame. The dog 20 has catch portion 22 which is adapted to be engaged by'the end 23 of vibrator 24 mountedupon ,the shaft 25, and the latter is given a continuous rocking movement during the winding operation from a suitable source of powernow well understood in the art.

Extending upwardly from the uprights 10' is a bracketor support 26, one at each side of the winding mechanism, and extending between the brackets or supports 26 is a shaft 27 on which is loosely mounted a trip arm 28 constituted as a lever adapted for vertically swinging movement about its axial support 27. In order to limit the downward movement of the trip arm or lever 28 a suitable stop is provided, which in the present instance consists .of a pin 29 extending from an arm 30 which is secured to the shaft 27 or one of the brackets 26.

Pivotally connected to the trip arm 28 at 81 is the dog controller '32 which is normally under the influence of a spring 33, one end of which is secured to the dog controller at 3d and the other endfto a fixed part 35. The fixed part 35 in the present instance of the invention is formed as a pro jection fr 211;} plate36 having an opening 37 and secured in adjusted position by a screw bolt 38, the result being that the tensioning effect of the spring upon the dog con- Mounted for adjustment on thetrip lever 28 is a stop plate 39 which may be secured in adjusted position on the trip arm by a bolt 40 which passes through an. opening or slot 41, as indicated in Figs. 1 and 2. The lower portion of the stopplate 39 has aprojection 42 (in-which the inner end portion .of the dog cont-roller normally rests under the action of the pl 3 In accordance with the present invention the dog controller 32 is connected to the dog 20. by' a rodor connection d8; The upper end of the rod 43 is connjected'to {thedog controllerat 4:4 and its lower end is-connected to the dog 20 througn, a pin #15 to which the "lower end 4:6 of theirod 43 is secured, the con strueti'on being such that during the'winding operation, as indicated the dog 20 1s msmtamed in an inoperative IGlatlOlYtO its thereon, as

associated vibrator and the winding of the yarn upon the yarn holder or core continues uninterruptedly. V

Secured to one of the arms 13 of the yarn holder is a bracket 47 to which is secured a trip finger 4:8, the upper portion of which is turned at 4.9 to present a hunter adapted to engage a projection 50 carried by the trip vibrator 24 with the result that they lifter frame 6 will be turned upon its'pivotal'support 5 and cause the lifter arm '2 to move outwardly about the pivot point 5 as a centre, thereby separating the yarn package from its driving roll.

It may be desirable at times to vary the amount of yarn contained in the yarn pacle ages, and tothis end the trip linger 48 is provided with'a slot 51 by which the trip finger is adjustab'ly secured to the yarn holder or bracket l'l'by the securing bolts 52. It will be evident from the adjustable character of the trip finger 4-8 that the yarn package may be varied in size because as theyarn package increases in size and lifts the yarn holder and trip finger, the position of the trip linger will define when and at what time the yarn package and its driving rell shall have separated into the position indicated by l.

Since the dog 20 is mounted upon the lifter.

frame 6 and the lifter frame turns about its 'niounting of the dog controller on the trip arm under the influence of the spring .troller .32 may be conveniently varied by adjustment of the plate 36 on the trip lever 28. i

From the construction described it will be apparent that a simple and yet effective means pivotal support 5, the dog. willtake a down yieldabl-e action of the dog controller peri mitsthe movement of thelifter frame without disturbance of any the operative rela- 'tions of the automatic winding stop motion.

As herein beforestated Figs. 2 and 3 show a slightly modified form of the details of the inventiom wherein the trip arm 28, which may be constructed substantially as in the preferred form ofcthe invention already described, .'has mounted on the dog controller 32 by the pivotal connection 31 before an d extending downwardly 'fromthe dog controller is'the rod orconnection'fi-g having interposed in its length yielding portion by means of a spring 54 the lower end portion of which may be properly connected to the dog 2O by 'means of a" pin55gextending therefrom/ I Pivotally connectedto the'trip arm 28 is a latch 56 which, as shown, Fig. 3, is'pivote'd at 57 v to a'bracket 58 secured to 'thetrip arm 28. The latch 56 has a catch end 59 which normallyoengages over the inner end portion of the dog controller 32, Fig. 3, and the opposite end portion of the latch 56 is pro-o videdwith hoe er abutment 60 which is adaptedto he engaged by the upper portion of the trip finger 48 when the yarn package has reached the predetermined'desired size. From the descriptiondescribed it" will be noted thatfth'e dog controller 32 in the modi fied form of the inve ntion normally holds the dog 20 in its operativejrelationwiththeas- .sociated vibrator, butwhen the trip finger 48 engages the end or shoe' 6O of thelatch 56 the catch end59 of the latchwill be disengaged, with the result that the outer end ofthe dog controller 32 will drop,thereby permitting the dog 20 to pass 'into operative relation 'with its associated vibrator, and through the train of mechanism already described as constituted by the lifter frame 6 and its associated parts, the yarn package will be separated 1 from its driving roll in amanner as hereinbeand the securing screw or bo passed therethroughits tore already explained.

' Inasmuch as thelatch 56 has the shoe 60 which normally holds the latch in engagement with the dog controller, it is desirableto control the amplitude of latch'movement, and in the present instance of the invention this is V effected by means :of a stop plate .61 having a laterally turned portion 62 upon which the shoe portion of the latch may restduring the winding operation. The stop plate 61 may be adjustably secured to the trip arm-28 by turned to its yarn winding position, the outturned end 66 of the pin limits to its amplitude of movement to effecta proper relation of the inner end latch. p
